PolySteel

The founders of Flow Smart are also the inventors of the industry’s first 316L filled PTFE material. Originally marketed by resellers as “Tef Steel”, the original compound is now exclusively available through Flow Smart. As the original molders, Flow Smart’s principles have developed an improved molding process that produces products with less porosity and markedly improved finishes.

PolySteel material offers an inert contact surface that withstands the most challenging SIP required in biotech and pharmaceutical processing. Seal Performance will remain as creep and cold flow is minimized with extreme T.

Flow Smart PolySteel Difference:

  • Only Stainless filled PTFE gasket with FDA approval.
  • Compound has been utilized longer than any other Stainless filled PTFE in biotech and phar- maceuticals.
  • USP Class VI tested
  • New tooling design produces better finishes and BPE compliant inside diameters.
  • Meets 3A Standards
  • Any geometry is available
  • Only Flow Smart PolySteel gaskets are produced from the compound that was known and speci- fied as Tef Steel or Tuf Steel before October 2003.
  • No animal derived ingredients are used to pro- duce PolySteel.
